warning: Swift error in module errors when using swift from Homebrew

[fgimian]

• Ran brew update and retried your prior step?
• Ran brew doctor, fixed as many issues as possible and retried your prior step?
• If you're seeing permission errors tried running sudo chown -R $(whoami) $(brew --prefix)?

Bug reports:

Hello there, I'm not sure if others are experiencing this issue, but after installing Swift with Homebrew:

brew install swift

When I try to start swift, I get a bunch of errors like this:

Any help would be appreciated 😄

I also see this. CC @aleksey @jdhealy @C-l-o-u-d and the venerable @mxcl in case any of you have any insights here on what we're doing wrong in https://github.com/Homebrew/homebrew-core/blob/master/Formula/swift.rb

[MikeMcQuaid]

Actually, I see the issue: run /usr/local/opt/swift/bin/swift rather than /usr/bin/swift and you'll not see these errors (they come from Apple's swift, not ours).

[fgimian]

Yup, that works, I feel so silly 😄 Thanks!

[MikeMcQuaid]

Well, I did the same thing at first so: don't!

[mxcl]

Seems like lldb is loading the wrong libraries, /cc @ddunbar

If we're doing wrong, we'll file a bug.

[MikeMcQuaid]

@mxcl Thanks! FYI it seems to be only reproducible when you have the CLT installed but not Xcode.

[fgimian]

@MikeMcQuaid that's exactly what my setup was also. After install Xcode yesterday, the version in /usr/bin works too 😄

However, another problem is that installing Python from Homebrow causes heads pf Python exceptions when running the version in /usr/bin:

e.g.

raceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'run_one_line' is not defined
Traceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'run_one_line' is not defined
Traceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'run_one_line' is not defined

I'm not 100% sure how to get around this as I need the Homebrew Python installed and wouldn't mind using the Xcode Swift while learning Swift.

Open to thoughts and ideas 😄

[jonathancbarros]

I am also getting exactly the same problem that @fgimian is when trying to run Swift directly on REPL.

[MikeMcQuaid]

@fgimian @JonathanBarrosGIT Please open a new issue.

[philosopherdog]

Run 'pip install six'. Apparently the REPL relies on Python and if you've been messing with the default version you may run into this error. #2712 .
